The Combined Gas Law Constant of Proportionality calculator computes the proportionality constant of a gas using the combined gas law based on the pressure, temperature and volume of a gas.
INSTRUCTIONS: Choose units and enter the following:
Constant of Proportionality (k): The calculator returns the temperature in Joules per degree Kelvin.
The Combined Gas Law associates the pressure, volume, temperature and a constant of a gas, based on a combination of Charles's law, Boyle's law, and Gay-Lussac's law. There is no 'official' founder for this law because it is a consolidation of the three other laws. The combined gas law states the ratio between the pressure-volume product and the temperature of a system remains constant (k). This constancy can be used when comparing different conditions using the same substances. The combined gas law is mathematically expressed as follows:
`(P_i V_i)/(T_i) = (P_(f) V_f)/(T_f) = k`
The Combined Gas Law calculator groups the forms of the Combined Gas Law formula in two ways as follows:
Since P•V/T = k, one can compute the initial (i) and final (f) states using the expanded version of the Combined Gas Law. The Pi • Vi/Ti = Pf • Vf/Tf tab allows the user to enter any five of the six values in the formula to compute the remaining one via the Combined Gas Law.
